摘要: 摘要:本文对基于改性聚丙烯酸酯的数码印花增稠剂的流变学特性进行了研究,掌握了各种改性剂、添加剂、消泡剂等添加剂和温度对其流变性能影响。结果表明:聚丙烯酸改性增稠剂呈现假塑性流体的特征,其体系的性能对电解质具有相对的稳定性,受非离子表面活性剂的影响较小。用幂率方程τ=k•γn对流变曲线进行拟合,通过一元非线性回归,得出该增稠剂在各温度下的粘度系数k和流变指数n,描述温度对其影响。用Arrhenius方程可以较好地描述温度对聚丙烯酸酯增稠剂流动特性的影响,其体系的流动能为2540J/kmol。

Abstract: Abstract In this paper, the rheological properties of modified polyacrylate thickener for digital printing were studied and the results about the effect of that a variety of modifiers, additives, antifoamers and other additives as well as temperature on the rheological properties were also understood. They showed that the modified polyacrylate thickener presents pseudoplastic characteristics, which has a relatively stability to electrolyte, and the non-ionic surfactant has little effect on the performance of the system. The flow curve was fitted with exponential mode τ=k•γn and treated with unary linear regression, and the Arrhenius equation can describe the influence of temperature on flow energy of polyacrylate thickener accurately.
